Hi Ramkumar and David,
     If this argument is only used for perf complement, how about make 
it hidden to user? Please refer https://lkml.org/lkml/2013/12/12/52 and 
https://lkml.org/lkml/2013/12/12/53 The two patches make --raw-dump used 
internally but hidden in output of '-h'.

     If you think we should expose it to user, I think we should make it 
work as an option rather than an argument, and make the output of it 
more readable,
how about the patch attached in this mail?

Example:
     # ./perf list cache --raw-dump
     L1-dcache-loads
     L1-dcache-load-misses
     L1-dcache-stores
     L1-dcache-store-misses
     L1-dcache-prefetch-misses
     L1-icache-load-misses
     LLC-loads
     LLC-stores
     LLC-prefetches
     dTLB-loads
     dTLB-load-misses
     dTLB-stores
     dTLB-store-misses
     iTLB-loads
     iTLB-load-misses
     branch-loads
     branch-load-misses
